Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN readers link Chemisting, a multi-year personal blog, for its March 2024 post on an open-source DIY flow battery kit. Comments discuss the kit's coulombic efficiency, inkjet paper and hydrogen gas management.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
if by 'the blog' you (or you and kennyblanken) mean https://chemisting.com/ , which post do you mean? the post you link to in that blog doesn't say anything about coulombic efficiency or inkjet paper, and there are four years of posts in the blog

on “An open-source flow battery kit”The author actually talks about ESS in a comment to the linked blog post from the article. Apparently their battery generates a ton of H_2 that needs to be managed. That could easily be the sort of thing that only is possible/realistic at large scales, thus eliminating sizing the battery down indirectly. https://chemisting.com/2024/03/15/an-open-source-diy-flow-ba...
